RADIOLOGY: FEMALE REPRODUCTIVE: Case# 34005: ?TORSED. 26 year old female with right lower quadrant pain, nausea, and vomiting. 1. Abdominal organs within normal limits. 2. Single living intrauterine embryo with a crown rump length consistent with a calculated sonographic age of 7 weeks 2 days +/-1 week which is 0 weeks 5 days greater than the patients LMP dates. 3. Large pelvic mass, consistent with dermoid cyst. Other differential possibilities are pedunculated fibroid or other ovarian neoplasm, though these are much less likely in a woman of this age. Free fluid is seen within the pelvis, and this may be secondary to torsion of the mass.
